View 1 RepliesI'm using Visual Studio Development Server (Visual Basic 2010) and it works fine. Now I've enabled NTLM Authorization because I want to test the website using a different user account. Now when I try to access the website I always get the following error page:
Server Error in '/' Application.
HTTP Error 403 - Forbidden.
Version Information: ASP.NET Development Server 10.0.0.0 .I'm using a test account which is a normal user within our domain. I've already set the access rights in my project folder to Full Access for this user but it does not help.
When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

View 3 RepliesWhen i use the FtpPutFile() of Wininet.dll to upload the files, there is no error returned (hence the function returns 'true'), but the file on the ftp server is just a partail image. Hence the upload process is not completed but the ftpputfile() cannot trap that. Any reason why? Or how to get trap those errors?

I have created a small app in VB.Net, Its was working well, I published it twice or thrice as well but now when I tried to publish it again I got following error:

Have seen some solutions for C# but do not know how to solve the issue in VB.NET.
Query:
Dim Query = (From t In myEntities.Bookings
Where(t.Ref = Someid)
Select t.People).Sum()
t.Ref field is an Int and so is t.People.
The SomeId value is the primary key of the related table. This issue is that there will not always be records in the Bookings table with a Ref value of Someid - so the query throws the following error.
I have seen others have got around this problem with catching the error, but from reading up on this and as per the error information it seems there should be a solution (in VB.NET) to cast the query or some of the fields in the query to nullable types?
Error is as follows:
The cast to value type 'Int32' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.
